A Sporting Clube de Portugal youth graduate, Lourenço made his professional debuts in England, serving two brief loan spells, first at Bristol City then Oldham Athletic, both in the Football League One. Additionally, he played and scored regularly for Sporting's reserves.
Lourenço made three appearances and scored once for Sporting in the 2003–04 UEFA Cup, making his Primeira Liga debut on 16 August 2003 in a 2–1 away win against Académica de Coimbra and scoring in the game (he found the net in the season's first three official matches). However, he gradually lost his importance in the squad, and spent the next years on loan to several clubs in the country.
Lourenço was released by Sporting in the summer of 2006, signing for Vitória de Setúbal. In the following January transfer window he moved countries again, joining Greek side Panionios FC, initially on loan. After signing permanently for two years he hardly received any playing time, being released on July 1, 2009.
After a short and unassuming spell back in Portugal, Lourenço moved abroad again, signing in January 2011 with UD Alzira in the Spanish third division. He reunited at the club with former Sporting teammate Beto, and both were released in June after the team's relegation, having appeared in a total of three games combined.
